The flag of Nepal is a concave pentagonal flag of red, white, and blue colour. It is used as both the state and civil flag of Nepal. Nepal has simply maintained its ancient tradition, while every other state has adopted a rectangular or square version in the European vexillological tradition. One popular interpretation is that the symbols of the moon and sun represent peace and hard work, respectively.
The red colour of the field represents bravery and Nepal's national flower, the rhododendron, while the blue colour of the border represents peace.
